In any event, a DigitalPoint Forums thread has a picture of someone advertising the network. The thing is, most people feel it is Shawn Hogan, the owner of Digital Point, advertising the network. I highly doubt that. In fact, it is probably an advertiser in the network, who wants to earn what is called "referral weight" to gain more "weight" in the network.
The more "weight" you have, the more your ads will be displayed in the network. So by this person having ads, he/she is hoping to increase his/her weight in the network and boos the visibility of his or her ads.
